摘要

Invasive plants pose a significant threat to biodiversity due to their proliferative nature in non-native environments. Their rapid and aggressive growth habit disrupts native plant communities, alters soil nutrient composition and microbial diversity, negatively impacting agricultural productivity. Invasive plants have a competitive advantage over native species and improved resilience to diverse environmental factors. Rhizospheric and endophytic microbiota associated with plants play significant roles in the development of several advantageous traits in plants. The invasive plant-associated microbiota plays a critical role in the host-plant establishment and proliferation by directly contributing towards growth through production of phytohormone-IAA, siderophores, ACC-deaminase, N2-fixation, and solubilization of inorganic phosphate. These invasive plant-associated microbiota also facilitates plant nutrient acquisition. Additionally, these microbes indirectly support plant health by producing bioactive metabolites which can modulate host plant microbial interactions in the rhizosphere. They also possess various functional activities, including bioherbicidal effects, antiherbivory, and herbicide resistance properties. This review explores the multifaceted role of invasive plant-associated microbiota in facilitating plant invasiveness and discusses their potential application as biofertilizers and biocontrol agents in sustainable agricultural practices.
